Have a large irrigation site, hotel water system, or commercial borehole that needs serious volume? The Hybsun 6SCSH17-5-3 solar hybrid well pump is the high-flow workhorse of the Hybsun line — a 3 kW submersible pushing up to 24 m³/h (400 L/min) from boreholes up to 55 m deep. True hybrid input: runs from a solar PV array (DC 540 V, VMP 620–750 V) by day, falls back to grid AC at 380 V three-phase when sunlight isn’t enough. Built for the kind of daily volumes a 3″ outlet implies — large-scale Cyprus agriculture, resort water supply, aquaculture, municipal distribution.

What It Is
For Cyprus customers running large irrigation sites across Nicosia and Larnaca plains, hotel complexes in Limassol and Paphos, agritourism resorts, aquaculture operations, or municipal water distribution in the Famagusta region — the Hybsun 6SCSH17/5-3 is the high-flow specialist of the Hybsun lineup.
A 3 kW AC/DC hybrid submersible with full AISI 304 stainless steel impeller, pushing up to 24 m³/h (400 L/min) from boreholes up to 55 m deep.
The hybrid controller runs from solar PV (DC 540V, VMP 620-750V) by day and 380V three-phase AC mains backup when needed — automatic switchover, no manual intervention, no battery required.
Smart-feature set: GPRS remote control via web/phone, Child Lock anti-stealing, intelligent self-cleaning, wireless long-distance start/stop without a float switch.
AISI 304 Stainless Steel Impeller
The 6SCSH series carries the same AISI 304 stainless steel impeller Hybsun uses across its premium US/USH lines — the construction tier matched to high-volume commercial pumping where reliability is non-negotiable.
Plastic impellers are purpose-built for clean groundwater at residential flow rates — Hybsun’s 3UP range delivers excellent value in those conditions. For commercial-scale flow through wells carrying mineral load or sand, AISI 304 stainless steel is the matched-construction option.
The entire wet end of the Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump is stainless: external jacket, stage casing, diffuser, impeller, wear ring, strainer, screws — all AISI 304 (the same corrosion-resistant grade used in food processing and medical equipment). The shaft is AISI 431, optimized for rotating-duty applications.
For a 3 kW commercial pump moving 400 L/min through Cyprus borehole water 6-12 hours a day, year after year, this construction grade is what delivers the multi-year service life that justifies the project economics.
At the heart of the Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump is a 3 kW AC/DC brushless permanent-magnet synchronous motor — engineered to run efficiently from either DC solar input or three-phase AC mains, with automatic switching between sources.
The motor uses centralized winding technology (machine-wound coils) for improved efficiency over conventional motor constructions.
It rotates on NSK Japanese-brand industrial bearings paired with an alloy mechanical seal, sealed by a double water seal arrangement that keeps the unit fully waterproof and leak-tight through years of submerged duty.
The motor sits in an oil-cooled AISI 304 stainless steel jacket — the same construction grade Hybsun uses across its premium SS-impeller pump lines.
The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump ships with its matched AC/DC hybrid controller in an IP65-rated enclosure for outdoor or pump-house mounting.
The controller accepts three-phase AC 380V input or DC 540V from solar PV (VMP range 620-750V), switching automatically between sources based on availability. MPPT tracking optimizes solar yield.
The smart-feature set distinguishes the hybrid platform: GPRS remote control via web/phone (start/stop the pump from anywhere — essential for remote Cyprus agricultural sites), Child Lock anti-stealing function (prevents unauthorized operation), intelligent self-cleaning, and wireless long-distance start/stop without a float switch — useful for elevated-tank installations across hotel and agritourism complexes.
At 3 kW commercial scale, a battery bank would be expensive. The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump uses 380V three-phase AC mains as the backup source instead — sunny daytime → pump runs from solar PV; night, overcast, very early morning → controller automatically draws from AC mains.
This is the practical difference between a hybrid pump and a DC-plus-battery setup. The hybrid topology uses the grid as effectively unlimited backup storage at no battery cost.
For commercial sites where 24/7 supply is non-negotiable — hotels, large irrigation, municipal supply — this is the architecture that keeps project economics realistic. For genuinely off-grid sites with no AC available, a battery is still possible via the DC side, though typically uneconomic at 3 kW.
Soft start (no inrush current damage to the motor), dry-run protection (pump stops if there’s no water, auto-restarts 30 minutes later), over-voltage, under-voltage, over-current, overload, phase-loss, high working temperature protection, and adjustable speed (frequency conversion). The controller automatically starts and stops the pump based on solar conditions. For boreholes subject to occasional dry-out, the automated retry function removes the manual reset trip — the pump tests the well itself every 30 minutes.

Who Should Buy This
The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump is Hybsun’s commercial-scale high-flow hybrid pump — engineered for installations needing serious daily volume that the 3-inch residential range can’t deliver. Buyer profiles below cover the typical Cyprus use cases across Nicosia, Limassol, Paphos, Larnaca, and the Famagusta region:
Hybsun’s solar well pump platform is consistent across all models in the range — MPPT controllers, NSK bearings, IP65 outdoor protection, CE/ISO 9001 certifications, 10 protection functions, and 2-year manufacturer warranty. Where models differ is rated power and flow envelope. The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump is the high-flow specialist, smaller siblings cover smaller-scale work:
Hybsun’s PV sizing rule applies uniformly across the entire Hybsun pump range: total array power must equal or exceed 1.3 × the pump’s rated nominal power.
For the 3 kW Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump that means at least 3900 Wp of solar panels — typically 10-12 modern 400 W modules.
The 30% reserve covers real-world PV losses: temperature de-rating in Cyprus summer, dust on the module glass, DC-side cable resistance, and module ageing over time. Most commercial installs land in the 5-7 kWp range for comfortable headroom.
The 6SCSH17/5-3 hybrid controller takes a PV string operating at 620-750 V VMP, with open-circuit voltage staying under 800 V.
That fits 14-18 modern 400 W panels wired in series — typical Vmp 36-40 V × 16 panels = ~600 V Vmp, with Voc ~45-50 V × 16 = ~750 V. Careful panel selection keeps Voc under the controller limit across summer-heat conditions.
Minimum array power: ≥ 3900 Wp (1.3 × pump power). For 24/7 hybrid operation via AC backup, the array can be sized to minimum 1.3× without over-engineering — the three-phase grid covers any solar shortfall.
Every submersible well pump trades flow for depth — the 24 m³/h Q.Max headline is what Hybsun rates the Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump at zero head, with output dropping as the lift gets taller. The figures below come straight from the manufacturer’s published curve, with daily output assuming a typical 6-hour Cyprus solar day (and a hybrid 24h mode where three-phase AC backup runs through the night):
“Total dynamic head” = static water level depth + pipe friction losses + vertical rise to your discharge tank. Pipe friction in a 3″ rising main is modest, but undersized surface pipework can cost you 10m+ of head — pipe diameter has to match the 24 m³/h delivery to avoid friction losses.
Putting those flow figures into commercial water-demand context:
For an exact sizing calculation, send CGP Solar your static water level, expected drawdown, pipe run length, storage tank height, and daily water demand — we’ll work it out against the curve.
For a commercial-duty hybrid pump operating in mineral-rich or sand-bearing water, stainless steel construction is the tier specifically matched to that duty profile. Sites with clean groundwater can equally rely on the plastic-impeller 3UP range — different conditions, matched construction grade. The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump uses full AISI 304 stainless steel across the wet end — the same corrosion-resistant grade used in food processing and medical equipment. Every wet-side component is stainless: jacket, stage casing, diffuser, impeller, wear ring, strainer, screws. The shaft is AISI 431, optimized for rotating-duty applications. For 24/7 commercial-scale operation in Cyprus sites with abrasive or mineral-rich water, this construction tier delivers the multi-year service life that justifies the project economics.
Same rotating hardware quality as the rest of the Hybsun premium range: NSK industrial bearings (the Japanese-brand bearings used as a standard across continuous-duty pumping equipment) pair with an alloy mechanical seal, and a dual water seal arrangement keeps the pump body sealed against ingress over years of commercial submerged duty. Hybsun captures the design intent in its datasheet as “offering the longer working life”.
The hybrid controller’s soft-start function ramps motor speed up gradually instead of slamming it to full current. For a 3 kW pump, the inrush-current spike that a non-soft-start motor would draw could exceed 15-20 kW momentarily — damaging to the pump itself and capable of tripping nearby breakers on three-phase grid-tied installations.
Soft-start eliminates that spike entirely — gradual motor ramp-up, smooth pressure build-up. For commercial Cyprus sites with sensitive electrical equipment nearby, this matters.
If the well draws down to dry (which can happen during peak summer demand on a 24 m³/h pump), the Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump stops automatically and retries 30 minutes later.
No manual reset. No burned-out motor. The controller handles this on its own, every cycle. For commercial wells where the cost of replacing a damaged 3 kW pump is significant, this protection alone justifies the hybrid controller architecture.
Typical CGP Solar project timeline: site survey and well assessment (2-5 days to schedule — we measure your well depth and static water level, and confirm the casing diameter), formal quotation (about 1-2 days), then on-site work — lowering the pump on rising main pipe with safety cable (half a day for typical residential depths), PV array and controller install above ground (one day), and commissioning under live solar with handover walkthrough (same day). CGP Solar handles installations across all five Cyprus districts — Nicosia, Limassol, Paphos, Larnaca and Famagusta.
CGP Solar specifies, supplies and installs the Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump across Cyprus — Nicosia, Limassol, Paphos, Larnaca and the Famagusta region.
Engagement scope: borehole survey with 6-inch casing verification, optional water-quality testing, PV array sizing against operational water demand, pump deployment on rising-main pipe with safety cable, three-phase electrical install, and full system commissioning (both solar PV side and AC backup wiring).
High-flow demand + bright Cyprus sunshine + Hybsun 6SCSH17/5-3 = 24 m³/h on tap, every sunny day, for years.

FAQ’s
Per Hybsun’s sizing rule, PV panels must total at least 1.3 × pump power. For the 3 kW 6SCSH17/5-3, that means at least 3900 Wp of solar panels — typically 10-12 modern 400 W modules. Most commercial installs land in the 5-7 kWp range for comfortable headroom against summer-heat de-rating. The PV string voltage has to land within the controller’s MPPT range: 620-750 V VMP, with Voc < 800 V. That fits 14-18 modern 400 W panels in series. For 24/7 hybrid operation via three-phase AC backup, the array can be sized to minimum 1.3× without significant downside — the grid covers any solar shortfall.
The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump doesn’t typically need a battery. Its hybrid design uses three-phase AC mains as the backup source instead. Sunny daytime → pump runs from solar PV; night, overcast, very early morning → controller automatically draws from AC mains. This is the practical advantage of the hybrid topology — at 3 kW commercial scale, a battery bank for night-time pumping would be very expensive (typical 24-hour reserve would need 60+ kWh of battery — five figures in cost). For sites with no three-phase grid at all, the project economics rarely support a 6SCSH17/5-3 deployment, alternative pump architectures usually make more sense.
The Hybsun 6SCSH17-5-3 solar hybrid high-flow well pump carries Hybsun’s standard 2 years manufacturer warranty. The pump is CE and ISO 9001:2015 certified. The AC/DC hybrid controller is IP65-rated — fully dust-tight and protected against pressurised water jets — making it appropriate for pump-house mounting, outdoor weather-exposed placement, or industrial environment installation.
